Is it possible to open an SSH session in PowerShell? Currently I use PuTTY but it would be nice if that were not required.

I know it's not natively supported but I'd love to see a solution too. –  egorgry Feb 18 '10 at 17:31

what's wrong with just calling putty.exe (or plink.exe) from command line? –  Javier Feb 18 '10 at 17:37

Javier: Let's start with plink being only a SSH client and completely lacking the terminal emulation features. –  grawity Feb 18 '10 at 19:32
    
+1, I'd like to see a solution myself. And for the most part I hate putty so much. (SecureCRT user) –  Urda Feb 18 '10 at 20:43

Not built in of course, but since Powershell can do anything .Net can do, there is a way.

Paid solution would be /n Software's NetCmdlets.

Free solution would be using the suggestions of this blog post.

I wrote a module for dealing with SSH sessions from PowerShell, based on the SSH.NET library found on CodePlex. It has New-SshSession to create connections (multiple targets using different credentials is supported), and then you can use Invoke-SshCommand to run commands against any number of target hosts. There's even an Enter-SshSession which has a very basic, interactive shell.

Download OpenSSH for Windows and choose to install just the client during the installation. The entire installer inlcuding the server is less 3MB and the client works just fine.

There are a lot of warnings on that project about the installer stomping the System PATH variable on Windows 7 & 8 - be wary! –  Patrick M Jan 22 at 17:02

If the target machine is a Windows box, then you can use PowerShell Remoting, instead.

It's definitely not the same as SSH. There are pros (bringing objects back over the wire!) and cons (what if the target is Linux?).

There's an alternative (free) PowerShell SSH solution, using a newer library implementation, see vBlog >> SSH Client Using PowerShell

I am still posting an answer to this question, because i found the accepted answer not suiting my needs at all (Only a paid solution or another that doesn't handle the terminal well).

So the obvious solution to this problem is to install cygwin. Do a minimal install if you just want ssh, but since powershell provides a basic level of compatibility with *nix shells (basic commands are still there, "/" for directories, etc), it's really possible to use cygwin stuff inside Powershell.

Cygwin install here

Cygwin? Bleck! Might as well fire up a VM... –  Urda Oct 14 '10 at 14:50
    
How so ? ssh is a windows compiled executable. If you wan't to interoperate with unix-y stuff, it shouldn't be a surprise that you have to install some libs for that. –  raph.amiard Nov 4 '10 at 10:18
    
See the answer by Ameer Deen, I think that is the best solution here and works great. –  Hosh Sadiq Feb 14 '12 at 6:46

I use Git http://git-scm.com/downloads

Includes a host of other tools like SCP and such that are useful too.

SSH and SFTP undoubtly represent industry standard in secure remote access application. Fortunally its possible that establishing a connect can be really quick and easy. Unfortunally the truth is that there are lot of possibilities to waste time with troubleshooting.

Unfortunally Windows has no a standard ssh client or deamon software on board.

This results in a zoo of more or less freaky implementations, open source, freeware, shareware and so on... sometinmes working sometimes not.

Within windows, its a money thing. Microsoft just does not want lot of users connecting to 1 lizensed computer easily. They want to sell their own solutions. So they dont offer native ssl.

cygwin is the best available solution.

putty / plink / winscp as client software. its also ok for scripting.

there are ssh deamons for windows integration, but the solutions are more or less instable.

the most stable way to have ssh deamon on windwos running is to run it inside a Linux VM, can be realized with a small linux distibution.

This doesn't really answer the OPs question. Can you edit your question to indicate why cygwin is a solution to the question posed by the OP? –  Twisty Nov 12 at 14:11
    
OP is not asking for alternatives other than PowerShell related solutions. –  cychoi Nov 12 at 15:11
